SPARE FUSES
FUSE PULLER
Your vehicle has spare fuses on the
back of the under-hood fuse box
cover.
I n f o r ma t i o n P r o v i d e d b y :
If you cannot drive the vehicle
without fixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
from one of the other circuits. Make
sure you can do without that circuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown fuse with a
spare fuse that has a lower rating, it
might blow out again. This does not
indicate that anything is wrong.
Replace the fuse with one of the
correct rating as soon as you can.
